Thank You For Choosing Kohler Company

We appreciate your commitment to Kohler quality. Please take a few

minutes to review this manual before you start installation. If you

encounter any installation or performance problems, please don’t

hesitate to contact us. Our phone numbers and website are listed on

the back cover. Thanks again for choosing Kohler Company.

Before You Begin

Observe all local plumbing and building codes.

CAUTION: Risk of personal injury or product damage. Cast

iron lavatories are very heavy. Get help lifting the lavatory into

place.

Prior to installation, unpack the new lavatory and inspect it for

damage. Return the lavatory to its protective carton until you are

ready to install it.

Inspect the drain and supply tubing. Replace if necessary.

These instructions are for installing the lavatory to wood frame

construction. For other installations, supply suitable bracing and

fastening devices of sufficient size and strength.

Do not substitute another sealant if one is supplied with this

lavatory.

Use the template supplied with the lavatory.

For replacement installations, make sure the existing cutout is the

same size or smaller than needed for the new lavatory.

Refer to the roughing-in information to ensure proper installation

for ADA applications.

Before You Begin (cont.)

Use these instructions for wall-mount, self-rimming and above

counter installations. Follow only the instructions that apply to

your installation.

You can choose between a wall-mount or countertop faucet

installation, depending upon the setting and styling you desire. A

wall-mount faucet is recommended.

1. Preparation

Install the water supplies and drain piping according to the

roughing-in information.

Wall-Mount Bracket Installations

Install the lavatory according to the instructions packed with the

bracket.

Self-Rimming Installations

Determine the faucet centerline location. Consider the faucet and

handle escutcheon diameters, the length of the spout, and the

clearance between the spout and the lavatory rim.

Calculate the faucet centerline measurement by ﬁrst dividing the

escutcheon diameter by 2, and then add 1/4″ (6mm) to the result.

If necessary, round the calculation up to the nearest 1/16″ (2mm).

Carefully draw the calculated faucet centerline on the cut-out

template. Choose the most suitable location based upon the

following factors:

•

compliance with all local plumbing codes

•

minimum 2″ (5.1cm) distance from the water stream to the

lavatory rim edge. This is important to ensure adequate clearance

for hand washing

•

a minimum 1/4″ (6mm) distance between the faucet spout and

the lavatory rim

Redraw the faucet centerline as needed to meet these

requirements.

Draw a line on the cut-out template a minimum of 2″ (5.1cm)

behind the ﬁnal faucet centerline. This is the minimum

backsplash locator line.

Preparation (cont.)

NOTE: Some Kohler faucets require a minimum of 2-1/2″ (6.4cm)

behind the ﬁnal faucet centerline.

Cut along the backsplash locator line on the template.

Cut out the template along the inside of the template cut-out line

labeled ″Self-Rimming Cut-Out″.

Position the template on the countertop to ensure clearance

between the lavatory, faucet, and backsplash.

Verify cabinet clearance beneath the countertop.

Use a pencil to trace the template on the countertop.

Check the clearance between the lavatory, faucet, backsplash, and

cabinet. Adjust the traced cut-out line accordingly.

Mark the faucet and handle centerline on the countertop.

Above-Counter Installation

Cut out the template along the inside of the template cut-out line

labeled ″Above-Counter Cut-Out″.

Position the template on the countertop.

For Wall-Mount Faucets: Provide sufficient spout overhang into

the lavatory basin. The faucet spout length must be at least 5″

(12.7cm) to provide proper performance.

For Countertop Faucets: Pay special attention to the spout and

handle ﬁt clearance when locating the faucet. Use the template to

locate the faucet spout hole centerline on the countertop. This

centerline is recommended to provide adequate clearance

between the edge of the lavatory and the spout.

Check for adequate clearance between the backsplash, faucet

spout and handles, and lavatory. Kohler Co. recommends a

clearance of at least 1″ (2.5cm). See illustration.

Refer to the faucet installation instructions for required clearance,

and mark the preferred faucet hole locations using a soft lead

pencil.

Trace the template on the countertop.
